We're arguing about scrounging around for basic resources here on Earth.
Less than a penny out of every tax dollar goes to exploring THE ENTIRE FREAKING REST OF THE UNIVERSE.
Anyone ever like any scifi intellectual property? Starcraft, Warhammer40K, Dune, Star Wars, Star Trek, Alpha Centauri, Freespace, any of the Gundam franchises, etc. etc. etc.?
Know what made all of those so fascinating?
SPACE TECHNOLOGY. Space technology and the prospect of meeting other forms of, perhaps more intelligent life than ours.
Is pursuing that sense of wonder not even worth a penny from your tax dollar?
with the right amount of pocket change, once upon a time, private individuals could go into space, but since they closed NASA due to budget cuts, well that's not even an option now. I mean, charge a few million and open NASA back up, problem solved. however other countries are entering space now. and sometime soon in the future they wish to colonize Mars (again)
I think both should be kept available. The private sector has many projects in the pipeline (some are very interesting to read). The Skylon is my favourite and the launch loop concept.
Ultimately the private sector will be involved in space tourism and projects involving satellites. Governments will move more towards interplanetary things such as the Mars rovers and research satellites such as space telescopes or gravity measuring satellites.
If private were possible, then it would be better. But private space travel doesn't have the same goals as public space travel. It's tourism, and getting utility satellites into orbit. No private company will ever build a satellite to monitor the earth's atmosphere, unless under a government contract.
Public-private partnerships can be a useful idea, though, like NASA using SpaceX's dragon to supply the ISS. One should just take care that the government is actually saving money that way.
Because it isn't taxpayer money and thus not me paying.
(In cases where private is financed by taxpayer money, this falls apart, obviously, but private firms can, sometimes, do the same thing cheaper than the government.)
